A kaleidoscope world: Abandoned buildings are distorted into 360-degree panoramas that seem to pop out of the screen

These intricate, psychedelic images may appear like something you might see while rolling on the floor after eating the wrong kind of mushrooms.

But their basis is firmly rooted in reality. They are 360 degree images of abandoned buildings, contorted to fit into single photographic frames.

Sven Fennema, 33, created the pictures, which include a forgotten villa and casino in northern Italy and abandoned churches in Poland.

Trippy: Although they look like the deepest throes of a ketamine trip, they are in fact real places

Eerie: This photo might give you the unnerving feeling that you are sinking into the ground

This creepy distorted image shows the inside of a long-ago raided tomb

In this, the inside of a church appears to recede into the distance from the centre in all directions, like something MC Escher might have imagined in his most-bizarre dreams

It is very hard to discern what this mind-boggling picture shows, but it is, nonetheless, spectacular...

He makes interactive walkthroughs with the images he captures but, compressed into a single frame, they give the impressions of monstrous eyes, balls of stone and the interior of dystopic sci-fi superstructures.

Images include a hotel ballroom belonging to an abandoned sanatorium in Germany, and an old winter circus in Belgium, but it's hard to tell which is which.

Mr Fennema, from Krefeld, near Dusseldorf, Germany, said: '60 degree panoramas are dear to my heart because I am able to invite visitors to follow me interactively on one of my trips and to see where my works are created.

'It is not possible to show these panoramic views as pictures in the classical way, because an interactive view is only possible online and on screen.

'Because of that I use a more abstract approach.

'Sometimes the actual place is no longer recognisable as such and thus leaves a lot of room for your own imagination.

A cooling tower gets the 360-degree treatment and, in the process, becomes something like the interior of some outer-space sci-fi dystopia

Mr Fennema told Mercury Press Agency that his love for exploring abandoned buildings started before he took up photography and it is an ongoing passion for him to continue to research and travel in the future.

I was interested in abandoned places even before starting with photography and always liked to explore and discover such places as it is like diving into history and opening time capsules,' he said.

'Before the photography I was only visiting places near to where I live but since my start of photography I am travelling all over Europe.

'The series is all an ongoing project as travelling through the abandonment is very fascinating for me as I love architecture and history.

'It is amazing to see how the time and decay changes a place, like when the nature strikes back and it shows a lot the impermanence of the work of man.

'What I find is kind of a hidden beauty, many people would just walk by.'
